You don’t have to look far for curve fitting software "Microsoft Excel" has all of the above mentioned functions built in it and it also gives the equations with R2 values. Excel has most of the engineering functions build in it that are required for your research.

I am very surprised that you are unaware of it and secondly you haven’t been directed by your supervisor / research fellow in this direction. ■

Well if you want something different then I would recommend software package called “Origin” you can check the details at www.originlab.com it is very similar to Excel but more engineering orientated and is packed with engineering functions. Then there are the MathCAD and Math Lab packages which are difficult to learn, but when you master them they are also very good.

Hope you find the info useful.

Try your friendly CAD draughtman. Splines and curves are embedded in nearly all CAD packages. You can even spline in 3D if you fancy that ■

Knowing from personal experience the difficulty of getting consistant and reliable data in the field of materials handling, going to the nth degree with curve fitting leaves me cold. Still, if it keeps them off the streets ....... ■
